"In a world getting used to extreme weather, 2023 is starting out more bonkers than ever and meteorologists are saying it’s natural weather weirdness with a bit of help from human-caused climate change.
Much of what’s causing problems worldwide is coming out of a roiling Pacific Ocean, transported by a wavy jet stream, experts said.
At least one highway in drought-mired California looked more like a river because of torrential rain from what is technically called an atmospheric river of moisture. New Year’s brought shirtsleeve weather to the U.S. East and record high temperatures to Europe as the Northern Hemisphere on Wednesday was more than 2.6 degrees (1.4 degrees Celsius) hotter than the late 20th century average. And this is after frigid air escaped the Arctic to create a Christmas mess for much of the United States."
